Application filed November 8,1929. Sen'al No. 405,607,

This invention relates to the method and means for attaching a coverv to a jar. 1 It has particular relation to the attachment of a cover which has a curved edge to aj ar which has a similar cross-sectional configuration.

For the purposeof illustrating my invention, I have shown it as applied'to a jar'which has a'circular cover and a cylindrical body portion, but of course it is obvious that the inventionis just as applicable to are which are notof this particular shape but in which, nevertheless, the edge of the cover and the corresponding edges of the jar are curved.

The embodiment of the ar which Ihave chosen to illustrate the invention includes a" cylindrical body portion 1 having a circu- 'lar cover 2, at the central portion of which is a knob 3. The cover 2 is adapted to rest on the upper edge of the body 4. I

Normally, of course, this cover may be lifted from the jar body as there is no positive connection between the'cover and the jar, and

likewise the cover may be rotated upon the upper edge of the jar body. l 1

- In order that the cover 2 may be held upon the upper edge of the jar body and may be prevented from rotating, l'haye provided a securing element which embraces the body and the cover and'is attached in the following manner: This securing element whi h is in theform of a ligature has one end 5 located at substantially the center of-the bottom 6 of the body of the jar g this securing element passes across the bottom in subtantially a radial line to the edge 7 of the jar body where it is seated in a notch 8. It then passes upwardly over the outerwall of the body at 9 and across the upper curved edge of the cover 2 at 10, thence across thetop of the cover at 11 in a line, which ifiextended would form a chord of the circular edge of the top. It then passes aroinidthe knob 3, traversing the top at 12, and again to the point 10 at the upper edge ofthe cover whereit crosses itself." It then passes downwardly at 13 along the outer face of-the body to the notch 8 where it mayagain cross itself. From this point it-passes entirely across the bottom of the jar at 1 1 in substantially a diametric line to the notch 15 in the lower edge of the jar body. Passing through this notch it passes across the face of the bodyat 16 and again across the outer edge of the cover at 16 ata point substantially opposite the point 10. It again traverses the cover at 17 from the point 16' to the knob 3. From the knob 3 it isagain carried at18 to the point 16 where itcrosses itself. Fromthis point it passes across the face of the body 1' at 20through the notch 15 where it may again cross itself. From this notch 15 it passes at 23 to substantially the center ofthe bottom and is engaged by its opposite end in a square hitch and passes at 24 to the edge of the body, through the notch 21 which is located substantially 90 degrees from. the previously described notches. From this notch it extends up wardly at 25 along the face of the body 1, where it crossesthe edge ofthe cover at 22. It then traverses the cover 2 at 26 and passes around the knob 3. From the knob 3 it again is led at 27 to thepoint 22 where it crosses itself and passes downalong the face of the body lat 28 to the notch 21 where it may again cross itself.

From this point it passes directly across the body at- 28 and through a notch 29.

Passingup over the *face of the body lat 30 ,:extends across the cover at 31 and again passes around the knob 3. From the knob 3 itis led again at 32 to the point 30 where it crosses itself, and fromthis crossing point itpasses across the face of the body at 33 and through the notch 29. From this notch it passes at34 to substantially the center of the 30 it crossesthe edge of the top or cover 12 at I The effect of this arrangement of the securing element is the production of a plurality of securing arms which embrace the cover and are anchored to the body portion of the jar. These securing arms in the illustrated embodiment are four in number, but their number may be of course increased or decreased.

In the present instance, the arms are shown as extending radially from the knob.

3 and comprise respectively the elements 11 and 12, 17 and 18, 26 and 27, and 31 and 32. These arms are drawn tightly over the cover of the jar and are anchored to-the jar body by the portions 9 and 13 and the corresponding portions which extend from each of the arms. These portions 9 and 13 and the corresponding portions which extend from the ends of the described arms are, as has been described, secured together beneath the bottom of the jar and are definitely located at oints on the edge of the bottom of the jar,

eing seated in the notches 8, 15, 21 and 29. It Wlll be noted, as has been described, that the elements of the securing arms converge from the knob 3 to the edge of the cover, so that were these arm elements extended they would each form a chord subtending an arc, less than one-half of the circumference of the cover. Moreover, the converging elements are crossed at the points where they pass over the edge of the cover.

The result of the arrangement is, describing it in connection with one of the arm elements by way of example, that the distance between the point of contact of the-element 11' with the knob 3 and the point 10 where this element passes over the edge of the cover, is less than any other distance between the first mentioned point and any other point on the circumference of the cover in a counterclockwise direction. This being true the element 11 will have no tendency to slip in a counter-clockwise direction on the edge of the cover; but as the distance progressively decreases in a clockwise direction there will be a tendency of'the element 11 to slip. This,

however, is prevented by the crossing of theelement 12, which definitely locates the passage of the element 11 over the edge of the cover; Likewise, the element 12 is prevented from moving in a counter-clockwiseposition to become loose by the coaction of the element 11. This is true of all of the elements or armsso that we have the securing elements as a whole definitely located in the notches on the lower edge of the jar and definitely located at points along the edge of the cover. The securing element as a whole will, therefore, be definitely held in its proper position and will in turn hold the cover upon the jar, and because of the action of the arm elements will prevent the rotation of the cover on the jar body.

This securing element is made preferably of a resilient wire, such as steel, which has a high tensile strength. For purposes which will later appear it is covered with material, such as silk, not only for appearances but also to insure that where the ligature crosses itself a frictional engagement will be produced, which will tend to maintain the engaged relationship.

In order that the joint between the cover and the jar'body may be sealed to prevent the escape of the cream and to exclude air from the cream, I have provided a seal between the cover 'or upper edge of the body of the jar, which includes a compressible element 33, which is preferably formed of tinfoil and completely covers the cream. This compressible element is of such a diameter that when the cover of the jar is in place the edge of the element will rest at 34 on the upper edge of the jar, and from the outer edge inwardly it will be depressed along a bevel 35 which is formed on the upper edge of the jar and against the inner face of the jar body at 36.

A second sealing element 37 which is compressible and resilient and which may be of celluloid, or another suitable material. is superimposed on the element 33, and takes a similar form when the cover is put on the jar body. These sealing elements are caused to take this form by a flange 38 onthe cover which is of a diameter only slightly less than the inside diameter of the jar body, the degree of difference being such that when the cover is forced into place the sealing elements 33' and 37 will be compressed between the flange 18 and the inner wall of the iar body.

Moreover, when the cover is drawn into place by the securing ligature thesealing elements 33 and 37 between the flange 39 of the coverand the upper edge of the jar body will be compressed and thus, as shown above a seal between the cover and the jar body will be formed. Furthermore, because of the fact that the securing ligature is resilient and under tension it continuously exerts pressure on the cover of the jar. and thus insures the continuedcompression of the sealing elements 33 and 37. And because of the fact that the sealing element 37 is resilient it exerts counter pressure against the ligature and further assists in maintaining the seal.

It will, of course, be understood that while I have described a particular way of applying the securing ligature to the jar it may otherwise be applied provided that application results in the construction which is defined in the appended claims.

What I claim is:

1. A commercia'lunit in the form of a package comprising a container having a closure provided with a projection, said closure being bound on the open end of the container by means of a ligature, said ligature being arranged in a plurality of pairs of parallel circular cross section and a circular cover provided with a knob, said cover being bound on the open :end of the jar by means of a ligature, said ligature being arranged in a plu-' rality of pairs of parallel strands at the sides of the jar and diverging strands at the top of the ar passing over the cover around said knob, the strands at the apex of the diverging portion crossing each 0ther,whereby one strand binds the other strand in place, said diverging portions on the cover being so arranged as to present a substantially symmetrical appearance to make an aesthetic ap peal to the observer.

3. A commercial unit in the form of a package comprising ajar having a cylindrical I body portion and a circular cover provided with a knob, said cover being spaced from the said body portion by means of a resilient sealing element, said cover being bound on the open end of the jar by means of a ligature of resilient material suitably covered to provide frictional engagement at points where the ligature crosses itself, said ligature being arranged in a plurality of pairs of parallel" strands atthe sides of the jar and diverging strands at the top of the jar passing over the said cover around said knob, the strands at the apex of the diverging portion crossing each other, whereby one strand binds the other strand in place, said diverging portions on the cover being so arranged as to present a substantially symmetrical appear- I ance to make an aesthetic appeal to the observer.
